The voice acting is not that bad; the woman in the house's voice could use some work, though.
The character designs aren't bad either.
The animation is just as alright, though the fighting scene could use some more attention. Apart from it feeling too quick.

Despite this, it has some plot on it. Haven't yet seen the very first episode, but when I have time, I will.

Messing around with SFM can be hard, but it can lead to interesting results. I understand this was mostly a test, but for that, this turned out okay. Yes, hands can be the hardest part of animation, as for placement and stuff like that.

You should keep experimenting with this stuff if you want to be someone in the big leagues for SFM users.
